Communities A community is classified as all living things (different species), living in the same place at the same time Key Properties of a Community: Diversity: Includes two components: Species richness= Total number of different species in that certain community Relative Abundance= How many of each species population are present in the community Species Diversity= Describes how diverse a community is by considering species richness and relative abundance Prevalent Form of Vegetation Within a community certain types of plants are present as well as these plants being structured and located in a specific way, this arrangement determines what animals lives in this community.

Ecology: Definitions Ecology: The scientific study of the interactions between organisms and their environment that determines the distribution and abundance of organisms Ecology is a science Environmentalism is a cause Conservation Biology is the integration of these two: using science to support a political cause Population ecology: experimental field approach: natural populations manipulated to test specific predictions arising from controversial ecological theory Organismal ecology: studies how an organism?s structure, physiology, and (for animals) behaviour meet environmental challenges Population: all the individuals of the same species within an ecosystem Population ecology focuses on factors affecting how many individuals of a species live in an area

Chapter 5 age structure A population?s age structure?the proportions of individuals at various ages?can have a strong effect on how rapidly it increases or decreases in size. biotic potential Species vary in their biotic potential or capacity for population growth under ideal conditions. carrying capacity (K) Together, biotic potential and environmental resistance determine the carrying capacity (K): the maximum population of a given species that a particular habitat can sustain indefinitely without being degraded. coevolution

Environmental Science Vocabulary ? Living Things in the Environment & Populations organism - a living thing habitat - an environment that provides the things an organism needs to live. biotic factor - a living part of an organism?s habitat. i.e. grass, plants, seeds, fruit, worms, bacteria, other animals abiotic factor - a non-living part of an organisms habitat. i.e. water, sunlight, oxygen, temperature, soil photosynthesis - the process in which plants use water along with sunlight and carbon dioxide to make their own food. species - a group of organisms that are physically similar and can produce offspring. population - all the members of one species in a particular area. The ?count? of one species in an area.
